About 2018 Harley-Davidson Road King Models
Every 2018 Road King, including the Road King Classic, Road King Special, and Road King Police, left the factory with a Boom! Box 4.3 or Boom! Box 6.5GT head unit. None of them shipped with factory Apple CarPlay, Android Auto, or a Boom! Box GTS unit, and there is no headset bypass for these model years.
Bring these bikes up to date with a genuine 2019-2023 Boom! Box GTS retrofit and a HogPlay GTS Bypass, or skip the swap with a dedicated aftermarket CarPlay radio. Either way, add a HogPlay Media Box for streaming audio and a USB Piglet for Mirror Link and AirPlay.
